Specify clock frequency for CycloneII FPGA

Hi, I want to specify a clock frequency for my counter(VHDL), to make it adds one every second.To simulate it I can simply generate a required waveform, but to configure it into FPGA I think I need a...

hi, I still have some problem I cannot figure out.I saw in the compilation report that the actual frequency of clockwas around 330 mhz.But the point is I don't think I have introduced the 330mhz clock into my counter, otherwise it should work. :confused:

Could you give some clue how to use a internal clock in my design?many thanks...
